I recently purchased a beautiful black 2004 automatic V6 Mustang. I'm really interested in putting a supercharger in it. It already has a Flowmaster exhaust that appears to be true dual.
I don't know a ton about cars. I'm a computer technician. I've been doing my best to research parts and kits, but I'm starting to get frustrated and figured I should go ahead and start asking questions.
(1)-First of all, is it okay to run an 11PSI intercooled kit on an otherwise stock engine?
(2)-Branching from that, will 110+ degree Arizona weather cause any problems?
(4)-Will I be able to run a supercharged engine on 87 octane fuel? If not, is 91 octane high enough?
(5)-What are these 3.73:1 gears? It seems like a ton of people have them. Is that something for a manual transmission or an automatic? What do they do?
I'll probably have a lot more questions, but answers to these would get me started at least. Thanks a lot.
Gears work on any transmission. Basically, there how fast your RPM's go up. The goal is to keep your RPMs in the powerband as long as possible. Gears will get you there ALOT faster.
Ok I'm also a v6 owner. Here's my personal advice, now, I'm not making enough money to buy a supercharger ( only 17...) but if I could I still woudn't. Why?
Because with 11 psi (and $4,000 down the drain) I would only have 270 HP. Heck, my bro's GT (03) has that stock. Now lets say I sold my car for ... $8,000 (only have 27,000 miles on it ). $8,000+ that $4,000... yea you get it. With $12,000 I could buy a decent GT, my model cobra (94-98) or a used Z28 that could kill the supercharged sixer. Now... lets say you supercharged a LS1....
Hey, thanks for the advice. That was actually the first thing I was thinking about before I purchased the car. The problem is that I'm 19 and the insurance for anything over a V6 is insane. I make a fair amount of money, but I can't be dumping $500-$700 a month into insurance for my car. The supercharger gives me a way around that.

hey, same situation with me dude, no cash for insurance, plus my v6 doesn't have the resale value. anyways, go for the supercharger if its an insurance issue, altho, turbos now aren't that bad on lag.
anyways, not to bash on Godlik3, cuz he did kinda get the gear thing right...
but:
a) stock '03 GTs DO NOT have 270hp.
b) 270 isn't realistic on a supercharger, should be closer to 300
c) supercharge an LS1? ****, slam a power adder onto ANY engine such as that and it'll be fast, although, last i checked, this was a 3.8L FORD engine he was talking about, in a general v6 ford mustang forum, not a pushrod chevy LS forum.

insurance wouldnt be a issue if you threw a supercharger on a 3.8 , it would be standard. With a intercooled supercharger and dual exhaust you should be pushing around 305 hp give or take at 11psi... and its totally safe on a stock engine. As far as the heat , i know a guy in new mexico with a procharged v-6 and he says the heat hasnt affected nothing but his a$$ from the leather seats ... and gears im not to sure about .

1) if it has an ATI ProCharger with an intercooler, yes -it's made for a car with stock internals.
2) you should get a dynotune, but the kit comes with a rich fuel map to insure you don't have detonation.
3) They're the same kit.
4) You MAY be able to run 87 octane with a dynotune that specifies 87 octane. I don't know. To run the kit and get the available hp, you'll need to run at least 91 octane -93 is preferable.
5) the most gear you should run is 3.45. you're better off with the stock gearing.

03 GTs have 260 at the crank.
270 hp is what the 94-98 V6 cars get after supercharging (150hp*1.8). the 99+ V6 cars generally get 345+ hp with an 11psi ProCharger. (80% increase, 193hp*1.8)
270 hp is from a non-intercooled Vortech at 5-6 psi on a 99+ v6 (50% increase).

He's got a 98 -his options are more limited.
But he can ask several buyers of used GTs about paying for the abuse of the previous owner.
Ask 74stangtogo.

Yea ... sorry... when I said 270 I was refering to MY CAR. In fact I did point that out...
And I was using the LS1 as an example, nothing more.
And I'm already paying $175 a month (insurance), might as well pay the extra $50 for the two extra cylinders
I def. agree with the used GT thing. My v6 is unmolested, now if I was to use that same $7500 (what my car cost) on a GT, it would be a v8 with 50,000+ miles and ran extremely hard by some kid ( like me ... if i had a GT i would be hot rodding 2...)
If my car was one year newer, and I had the money to blow on somthing, I would geta turbo. But in my situation it just isn't worth it.
I'm actually paying about $305 a month for insurance, where as a GT would be $500+. I actually called my insurance company to check.
So, what I'm gathering from all of this is that a supercharger would put me in a good 300+ HP range with little risk as long as I follow the instructions closely.
Today I've come up with a couple of new questions that are semi-related.
(1)-I heard that there's a way to make it so both of my back wheels spin instead of just one. Is there a major difference in traction? When I hit the gas hard my car does peel out for a couple of seconds. Where can I find the parts for this?
(2)-What are some other recommended mods to get the most out of a supercharger? If a supercharger can get me to 345 HP, would it be possible to get close to 400 HP while keeping my car good for daily driving?
(3)-Can I install this thing myself? I'm willing to do research and I'm a fairly mechanical person, but I'd need to be able to install it in a single weekend. How complicated would it be?
"Heck, my bro's GT (03) has that stock.". i specified that your car would have 270hp w/ a s/c setup, then said your bro's car has 270hp stock...
anyways, to make both wheels spin at the same speed you're thinking of a t-lok. relatively cheap, they're used to get a good launch so you don't end up going sideways too much and losing equal traction off the launch.
also, you could get the engine up to 400hp, as the block itself can handle a hell of a lot more than that stock, but if i'm not mistaken, you'll need to start getting forged internals, reinforcing some parts, and definitely need to replace the rear differential on that.
*edit* also, to get that power to actually hook up at the wheels, you'd need a decent set of tires

T-loks are good but why dont you just go ahead and buy a limited slip differential (LSD) such as the detroit true trac? A complete aftermarket LSD is much more durable than Fords T-lok.
Edit: Also my insurance started at 290 with the V6. I could imagine it would have been 350 or more for me with a V8. And what they said to you about the gears is true. I had this explained to me when I thought about going up on the gear ratio when getting a supercharger. They expalined to me that Id be better of with the stock gearing if I used forced induction later. Gears are good for a car thats NA but if you get a supercharger it will give you the low end torgue that the gears would, so you dont really need them as much.
And yes you can install the supercharger your self. But it does get very involved. Youll have to replace the injectors which requires you to remove the upper intake to reach them. You will also have to replace the fuel pump and the mustang has a in tank pump, so youll have to lower the gas tank from under the car to get to it. Some of its easy, but some of it you cant do by yourself. Its recommended you get extra people to help. It can be done in 8-10 hours. Or if you dont have that much time in one day it could become a 2 day or week long project easily. I havent put a supercharger in yet, but I plan to soon.
I have a 99 v6 5-speed and I'm considering putting turbos on it. One of my friends has a twin turbo 300zx (It's a freakin rocket already) and he wants bigger turbos. He said when he buys them he will sell the two turbos and intercoolers to me for 3k, which is a pretty good deal. I'll just have to talk to TMA Turbo or something to get set up with the pipes and a few other odds and ends. But what will running 11-12 psi from intercooled twin turbos do to my mostly stock engine? And can I take the entire rear axle from a 99 gt and put it on my 6 with little/no modifications?

Auburn reissued their LSD, so now there are two -Auburn and Detroit Locker.

I doubt the 300ZX turbos can be used with the Mustang. The 300zx is a 3.0L isn't it?
Everything from a GT or Cobra will bolt on to the six -it's the same chassis.
